NETA Level 2 Certified Assistant Electrical Testing Specialist 認定 NETA_2 試験問題 (Q62-Q67):

質問 # 62
Polarization Index (PI) is defined as the ratio of insulation resistance measured at:

正解：D

解説：
Polarization Index evaluates insulation quality over time and is calculated as:
PI = IR at 10 minutes ÷ IR at 1 minute.
NETA Level 2 technicians use PI testing to assess insulation dryness, cleanliness, and aging.


質問 # 63
A battery bank consists of60 cells, each rated2 V. What is thenominal DC voltageof the battery bank?

正解：C

解説：
Battery bank voltage is calculated by summing the individual cell voltages in series:
60 × 2 V =120 V
NETA Level 2 technicians routinely test station batteries used for control power and protection systems.
Accurate voltage verification is critical for ensuring breaker tripping capability and relay operation during loss of AC power.


質問 # 64
Using the provided diagram, what is thetotal circuit resistance?

正解：C

解説：
Total circuit resistance depends on how resistors are connected. Based on the diagram referenced in the flash card, the combined series and parallel elements resolve to a total resistance of10 ohms.
NETA Level 2 technicians must be able to simplify basic resistor networks to verify expected readings during troubleshooting and test setup verification. Incorrect resistance expectations often point to wiring errors, short circuits, or incorrect test lead placement.


質問 # 65
A 3-phase, 480 V system supplies a balanced load drawing50 A line currentat a0.85 lagging power factor.
What is thetotal real powerdelivered to the load?

正解：D

解説：
Real power in a three-phase system is calculated using:
P = #3 × V_L × I_L × PF
P = 1.732 × 480 × 50 × 0.85
P #35,300 W (35.3 kW)
NETA Level 2 technicians must be able to correctly apply three-phase power equations during load verification, commissioning, and troubleshooting. Errors in power calculations can lead to incorrect conclusions regarding transformer loading, feeder capacity, and protective device coordination.


質問 # 66
A piece of wire that is0.001 inchesin diameter and12 incheslong is defined as onemil-foot.

正解：C

解説：
Amilis one-thousandth of an inch (0.001 in). Amil-footis a reference unit used in conductor resistance calculations. It describes a conductor that is1 mil in diameter and 1 foot long. Since 12 inches equals 1 foot, the statement is correct.
This unit supports standardized resistance formulas such as:
R = (K × L) / CM
where R is resistance, K is the resistivity constant, L is length, and CM is circular mil area. While technicians in the field often rely on tables and software, NETA Level 2 fundamentals include understanding what these units represent so results and conductor resistance expectations can be sanity-checked.
This concept also appears when evaluating long cable runs, verifying conductor sizing, or interpreting low- resistance measurements where expected values are small and sensitive to length and cross-sectional area.


質問 # 67
